Be it known that1I; CHARLES H. ROBERTS, a' citizen of the United States, .residing at Salt Lake City, in the county of :Salt Lake and State of Utah, havevinvented certain new and useful Improvements in Waveand;

Current Motors, of whichthe following is a specification.

My invention relates to be placed on a beach or in a flowing stream and utilize the force of the flowing water when applied on a plurality of spaced apart rectangular blades each of which. is fastened on a chain belt mounted to present adjustable parallel leads of said belt.

These objectsI'accomplish with the mag chine illustrated in the accompanying draw ings in which similarletters'and numerals of reference indicate like parts throughout the several figures and as described in the specification forming a part ofthis applica-; tion and polnted out in the appended claims;

In the drawings in which I have shown a substantial embodiment -of my invention,

Figure 1 is a side elevation of the machine,-

Fig. 2 is an end elevation of the same. Fig. 3 is a plan view of one endportion showing parts of the frame on which the machine is mounted. V y

The present invention is intended for use on an ocean beach whereby theforce of the waves alone or the force of the waves and the undertow may both be used to develop power, or as will be obvious it maybe used in a running stream and the gravity flowof the water applied to the lower lead of: I.

' 3 to the desired positionfor the run of the the belt to develop power thereby.

I mount the machine on a frame consist: ing of parallel strlngers A, supported on posts B. Onthe inside of said posts B are" secured the angle iron'supports'1 which are spaced apart to form a vertical channel therebetween and ,in which channel the end frames C are slidably mounted for vertif cally adjusting the chain belt to thefpitch of the beach. Between each pair of said] angle irons 1 is mounted one of the axles 4:

of the lower sprocket wheels 2. To one of said angle iron supports 1 at each corner of the frame 1s pivoted one end of one-of theupper sprocket wheel braces 3. The upper; V

' of the land where used andiad ustablejby sprocket wheels 5 are secured on an. axle 6 which is journaled inbearings 7' that are WAVE nirialcnnrtrnrivioronf Y Specificatien of letters' l atentf.

into belt by the blades-'9 which are fastened,

vthereto-atanangle relative to the run of the said belt." The reachesofsaid-chain belt are tobekept parallel and the spaeefbet'ween .the reachesis adjustable -zby raisingao r lowering the free ends of the said braces '3 which 1's accomplishedfby rneans of manually operated ratchet pinions 10, the teeth of which engage the'racks 11'. The said pinions 10 and racks 11 are each mounted in a *fastenedlon said braces; .3; pair'of "end less. chains '8 s are operatedover the said *sprocket wheels-2- and ",5; and are formed frame D which in turn is mounted on the i cross piece 12 of theframe C. The said is also secured on said axle 6fand a chain- 16 carried thereon carries or imparts the power developed to machinery not shown;

The operation of my machine is as follows: I v I r r When it is used on an ocean beach the leadsof the chain belt are adjustedntmthe pitch of the beach byadjusting-the vertical position of the said frames "0 relative tofthe angle irons land fastening the said frames C when so adjusted. The adjustment of the reaches of'the said chain belt is to each other and as .to the waves and depth of the under? J tow as madeby raising or lowering the free ends of the braces 3, which is done by rotat ingv the pinions 10 and raising or lowering the racks 11 and by means of the said' U- shaped pieces 14 adjusting the said braces 7 upper lead of the, chain belt and blades 9 c in order that the incoming waves may act."

on the blades 9 of'the upper lead'while the I" lead of said chain; .When using my.ma-' chine in a running stream I use only the undertow acts on the blades 9 of the lower 1 blades 9 of the lower reach of the chain and 7 so adjust the frames 0 as to bring said I 1 blades 9 in contact with the flowing wateri;

And I may use any desired length of chain .j

by providing supp'ortingmeans. I,

I thus provide a new and novel machine;

adapted for use at either-place which? is" compact, adjustable as to the pitch or lay new and novel means as toi'the relative leads 70 pinions-lO are rotated by the hand cranks Having thus described myinventionand its operation I desire to secure by Letters 'Patent and claim '1.
